Arai polymer.Polymerization When considering the mechanism of reactions and the chemical structure of the polymer, and then found that the polymer can be split into 4. arai type details are the following: Arai polymer step or condensation. Arai polymer chain model. medical or Arava Arai. polymer an Onsen. Arai polymer coordination model. 1. polymer arai. Advanced or condensation (Step or Condensation Polymerization). Arai polymer 1.1. advanced that a straight line (Linear Polymerization Step.) In preparing this type of polymer, the number of Mu terminal function (functional) is very important, for example, the ester preparation from the reaction between Mu carboxylic and sorption in the, molecules of acetic acid and ethanol, both molecules have only one function, Mu Mu Terminal (monofunctional compounds) the product of the reaction is water, ethanol and acetate thina therefore equation. But because both precursors there is only one terminal functions, Mu Mu. ELSA thina acetate occurs, so no Moo function terminal can occur as a reaction to the polymer. When considering the reaction between the acid pour yields (terephthalic acid) hotel and ethylene naklai (ethylene glycol), which calls the two molecules is Terminal 2 Mu functionality (difunctional compounds) ester resulting from one end of amino silicone carbide reaction with handmade tell one end of hydroxyl silicate called an Dai (dimer), which can occur as a reaction to the Merlin trilogy (trimer) or Tetra (tetramer) which has among its functions, Terminal 2 Mu (difunctional tetramer) and the following reactions have a high molecular weight polymer that has a linear structure. If use a terminal that has among its functions the nautiloids, two or more villages will be the polymer with the branches, such as when using the acid reaction with handmade Hotel pour yields glycerol (glycerol: HOCHB2BCH (OH) CHB2BOH), which has among its functions, Terminal 3, the product is a polymer with non-ester. 1.1.1. condensate polymer (Polycondensation) There is a small-molecule reactions were eliminated during the reaction, such as a molecule of water is removed during the preparation of linear ester polymer. Therefore the equation below. When the R1 and R2 replaced by hydrocarbon In addition, Ester polymer can also be prepared from a single type of polymer with ornamented Moss function terminal two villages (e.g. hydroxy carboxylic acids-) Polyamide polymer can be prepared from the condensation reaction between MOSS are ornamented Moo Moo 2 functions, such as amines and tell. 1.1.2 polymer Addis ADI (Polyaddition) Arai. polymer is between MOSS are ornamented Moo Moo 2, but does not have the function to eliminate small molecules during the reaction. For example, the Polyurethane polymer (polyurethanane), prepared from the reaction between isocyanates subdirectory (diisoscyanate) and all (diol) Urea polymer (polyurea) is the reaction of isocyanates (diisocyanates) with amines (diamines). The application of Diels-Alder reaction leading to preparation of polymer such as polymer arai of the Cole-Dai Sai nata (cyclopentadiene) equation. Arai polymer 1.2. step that is not linear (Non-Linear Polymerization Step.) เป็นปฏิกิริยาระหว่างมอนอเมอร์ซึ่งมีหมู่ฟังก์ชันนัลมากกว่า 2 หมู่ ในขั้นแรกจะได้โครงสร้างของพอลิเมอร์ที่มีกิ่งก้าน และหลังจากนั้นจะมีการเพิ่มขนาดหรือน้ำหนักโมเลกุลอย่างรวดเร็ว และในที่สุดแล้วจะได้พอลิเมอร์โครงสร้างแบบร่างแห ซึ่งมีสมบัติแตกต่างจากพอลิเมอร์แบบเส้นตรง ยกตัวอย่างเช่น ปฏิกิริยาระหว่างไดคาร์บอกซิลิก แอซิค (dicarboxylic acid : R(COOH)2) และ ไตรออล (triol : RP'P(OH)3) ซึ่งมีหมู่ฟังก์ชันนัล 3 หมู่ ได้พอลิเมอร์โครงสร้างแบบร่างแหดังนี้ พอลิเมอร์โครงสร้างแบบร่างแห (Network Polymers) Polymer type formaldehyde (formaldehyde-based resins) is a polymer which is prepared first drafts to main by polymer arai. step and used trade. Starting from preparation of polymer with low molecular weight After that, the polymer is flowing under pressure and heat in the mold (mold) for forming a polymer structure, draft and as the purveyor of mold because the formaldehyde has among its functions, the 2 will cause the draft structure, the Cape is a precursor (coreactants) with the number of Mu terminal function (functionality, f) for more than 2 typically, the popular use of phenol (f = 3), urea (f = 4) and melamine (f = 6).
